Non-ionic surfactant blend based on ethoxylated oleyl alcohol and propoxylated stearyl alcohol.
Excellent emulsifying and stabilizing performance in oil-in-water systems across broad pH and electrolyte ranges.
Low foaming profile suitable for high-shear industrial processing and rinse-off formulations.
Good compatibility with anionic, cationic, and amphoteric surfactants as well as common polymers and actives.
EcoVadis-recognized sustainable sourcing profile and compliance with major global regulatory frameworks (e.g., REACH, COSMOS).
Industrial metalworking fluids — particularly semi-synthetic and micro-emulsion coolants.
Agrochemical adjuvants for aqueous suspension concentrates (SC) and emulsifiable concentrates (EC).
Home care liquid detergents and hard-surface cleaners requiring stable, low-foam emulsification.
Personal care cleansing bases and leave-on emulsions where mildness and sensory elegance are critical.
Paint and coating additives for pigment dispersion stabilization and water-thinnable resin emulsions.

Q1: What is the primary function of Emulphor OPS25 Emulsion in formulations?
A: Emulphor OPS25 Emulsion is a nonionic oil-in-water emulsifier designed to stabilize aqueous dispersions of hydrophobic actives, oils, or waxes—particularly in personal care and pharmaceutical applications where mildness and clarity are valued.
Q2: Is Emulphor OPS25 Emulsion suitable for rinse-off or leave-on cosmetic products?
A: Yes—it is commonly used in both rinse-off (e.g., shampoos, body washes) and leave-on (e.g., lotions, serums) formulations due to its gentle profile, low irritation potential, and ability to deliver stable, low-viscosity emulsions without requiring high shear or co-emulsifiers.
Q3: How should Emulphor OPS25 Emulsion be incorporated into a formulation?
A: It is typically added to the aqueous phase at room temperature or slightly elevated temperatures (up to 45°C), followed by gentle mixing. Pre-dilution with water may improve dispersion uniformity. Avoid prolonged high-shear processing unless required for specific texture development.
Q4: Does Emulphor OPS25 Emulsion require pH adjustment or compatibility testing with common preservatives?
A: It exhibits broad pH stability (approximately pH 3–10) and generally shows good compatibility with widely used preservative systems, including parabens, phenoxyethanol, and isothiazolinones—though compatibility should always be confirmed in the final formulation under intended storage conditions.
